WhiteSands is the enormous desert that surrounds DisCity on all sides. Named for its white gravel particles, WhiteSands is a harsh natural environment continuously ravaged by a mega-sandstorm called the Tide of Ashes. There are two known major population centers in WhiteSands: DisCity upon the DisSea and Fraser City upon "the oasis". Any other human population in WhiteSands is found in trading posts and intelligence stations near official trade routes through the desert, or in small settlements built up around oasis or desert bandits who travel between the oasis and official routes. These roaming bandits refer to the area not covered by official routes as the "high seas". WhiteSands is technically considered part of DisCity's territory, reflected in the fact that only DisCity's official sand ships are allowed to use the official routes, but its harsh environment makes it a no-man's-land and issues in WhiteSands are administered by the Outland Affairs Bureau. WhiteSands is navigated by enormous vehicles called sand ships or sand cruisers.
The existence of the desert predates Nightfall, but its environment changed significantly after it was struck by the Perishing Star. The city of Maria was reduced to the present-day white desert frequented by monstrous sandstorms. In the depths of WhiteSands, monstrous figures known as Apostles of Ash walk through the sandstorms, always approaching the DisSea. Further dangers are posed by bandits that attack trade vessels, as well as enormous sandworms.
